While previous research linking bone cancer and obesity has been inconclusive, a new prospective study provides additional evidence of obesity increasing a woman's risk of developing multiple myeloma, a type of bone cancer. Researchers from the University of Minnesota Cancer Center reviewed data from 37,083 postmenopausal women who were followed for 16 years. They found several characteristics that indicated a greater risk for developing the cancer. Women with a body mass index (BMI) >30 (obese) were 1.5 times as likely to develop multiple myeloma as women with a normal BMI. Among that group, women with the highest weight, waist size, and hip size doubled their risk for developing the cancer. Considerable research has been completed linking obesity to other cancers, but linking obesity to multiple myeloma is a newer theory.
